Acknowledgements
I begin by thanking Prof. John Thome for providing the opportunity to do this thesis
and for his guidance and support. Special thanks go to Wolverine Tube Inc. and
Wieland Werke AG. for supplying the tubes as well as the other industrial partners,
Trane and Carrier, all of whom contributed to finance this study.
I also thank my colleagues at the LTCM, who have created a fantastic work atmosphere
and the many accumulated hours of coffee time. Special thanks to Marcel Christians
and Jonathan Oliver for all their input during our time together. Thanks to the
entire staff of the ATME workshop for their technical work. Special thanks to Laurent
Chevalley, who performed the majority of the work on the facility, and with whom
I shared many hours exploring single tracks and mountains. Thank you to C´ecile
Taverney and Nathalie Matthey-de-l’Endroit for taking care of the administrative
work and their never ending smiles. Finally, I thank my family for their encouragement
and support and give a special thanks to Juan for her endurance and love.

Abstract
plexity of two-phase flow boiling on a tube bundle presents many challenges to the
understanding of the physical phenomena taking place. It is important to quantify these numerous
heat flow mechanisms in order to b
